Using The Machine - Husqvarna DM 230 Operator's Manual

Using the machine

• The machine has a very high torque. This demands good
concentration during work, as serious personal injuries
can occur if the drill bit suddenly jams.
• Keep your hands at a safe distance from the drill spindle
and drill bit when the machine is running.
• Keep an eye open for oil or water leakage. If water or oil
trickles out from the leakage hole on the top of the pinion
neck, the seals must be replaced
Handheld drilling
!
WARNING! Do not perform handheld drilling
in first gear as the machine has a powerful
torque that can result in personal injuries
should the drill bit jam.
• Always use a drill bit with a max. diameter of 75 mm with
handheld drilling. The larger the drill bit the greater the
reaction if the drill jams.
• Always make sure you are standing firmly when carrying
out handheld drilling.
Stand drilling
• Always use a drilling stand if drilling is to be performed
from a ladder or scaffold.
Handheld drilling in these situations is full of risks, as the risk
of falling is very high if the drill bit jams.
• Make sure that the stand is secured correctly.
• Make sure that the drilling machine is secured correctly in
the stand.

WORKING TECHNIQUES
Drilling outdoors

Drilling in ceilings and the like

like in order to prevent water penetrating into the machine,
but do not cover the air intakes and air outlets.
IMPORTANT! The air intake must not be covered.
